I agree: Vista is a complete waste of time, but Microsoft have the monopoly so we're all going to eventually take the plunge. Say bye bye to any P2P, any software that doesn't pay M$ a licencing fee, most AV software and game mods.
I really don't see why (other than money) Microsoft has made Vista so incompatible. I guess they do it because they can, and they have marketing so cleverly worked out, that there will never be a Mac or Linux 'revolution.'
